EnVision

EnVision is a forthcoming European Space Agency mission aimed at exploring Venus in unprecedented detail, building upon the legacy of previous Venus Express and Magellan (spacecraft) missions. The mission is designed to study the atmosphere of Venus, its geology, and climate, providing valuable insights into the planet's evolution and potential habitability. EnVision will work in tandem with the NASA DAVINCI+ and VERITAS missions, as well as the Japanese Aerospace Exploration Agency's Akatsuki (spacecraft) and Planet-C, to create a comprehensive understanding of Venus. The mission's findings will also be compared to those of the Soviet Union's Venera program and the United States' Pioneer Venus project.

Introduction

EnVision is part of the European Space Agency's Cosmic Vision program, which aims to explore the Solar System and beyond, including Mars, Jupiter, and Saturn. The mission's development involves collaboration with NASA, the Canadian Space Agency, and the Japanese Aerospace Exploration Agency, among others, such as the German Aerospace Center and the Italian Space Agency. EnVision's launch is scheduled to coincide with the European Space Agency's Ariane 6 rocket, which will also carry other European Space Agency missions, including the JUICE (spacecraft) and the Hera (space mission) to Ganymede (moon) and Didymos (asteroid). The mission's success will rely on the expertise of renowned space agencies and research institutions, such as the Jet Propulsion Laboratory, the Goddard Space Flight Center, and the University of California, Berkeley.

Mission_Objective

The primary objective of EnVision is to investigate the surface of Venus and its atmospheric composition, with a focus on understanding the planet's geological history and climate evolution. The mission will study the volcanic features of Venus, including Maat Mons and Maxwell Montes, as well as the pancake domes and lava flows that cover the planet's surface. EnVision will also examine the atmospheric circulation patterns of Venus, including the polar vortices and the equatorial jet stream, in comparison to those of Earth, Mars, and Jupiter. The mission's findings will be used to inform future space missions to Venus, such as the NASA VERITAS and DAVINCI+ missions, and will contribute to a broader understanding of the Solar System and its planetary formation.

Spacecraft_Design

The EnVision spacecraft is designed to withstand the extreme environment of Venus, with temperatures reaching up to 462°C and crushing pressures of up to 92 times that of Earth. The spacecraft will be equipped with a heat shield and a radiative cooler to maintain a stable operating temperature. EnVision will also feature a high-gain antenna to communicate with Earth and a solar array to generate electric power. The spacecraft's design is based on the European Space Agency's Venus Express mission, which successfully orbited Venus from 2006 to 2014, and will incorporate lessons learned from other space missions, such as the NASA Magellan (spacecraft) and the Soviet Union's Venera 13.

Scientific_Instruments

EnVision will be equipped with a suite of scientific instruments designed to study the surface and atmosphere of Venus. The mission will feature a radar instrument to map the topography of Venus and a spectrometer to analyze the atmospheric composition. EnVision will also carry a camera system to capture high-resolution images of the Venusian surface and a lidar instrument to study the atmospheric circulation patterns. The mission's instruments will be designed and built by a team of international research institutions, including the University of Oxford, the California Institute of Technology, and the Max Planck Institute for Solar System Research, in collaboration with space agencies such as the Canadian Space Agency and the Japanese Aerospace Exploration Agency.

Launch_and_Operation

EnVision is scheduled to launch in the late 2020s on an Ariane 6 rocket from the Guiana Space Centre in French Guiana. The mission will take approximately 15 months to reach Venus, after which it will enter into a polar orbit around the planet. EnVision will begin its scientific operations shortly after orbit insertion, with a planned mission duration of at least 4 years. The mission will be controlled by the European Space Agency's European Space Operations Centre in Darmstadt, Germany, with support from NASA's Deep Space Network and the Japanese Aerospace Exploration Agency's Usuda Deep Space Center. The mission's success will rely on the expertise of renowned space agencies and research institutions, such as the Jet Propulsion Laboratory, the Goddard Space Flight Center, and the University of California, Berkeley.
